WebFeb 22, 2013 · In your case you don't need to create a new plan at each iteration, unless the dimension of the data changes. You would rather do the following: #pragma omp parallel default (none) private (m) shared (numberOfColumns, numberOfRows) { // create pointers double *inputTest; fftw_complex *outputTest; fftw_plan testPlan; // preallocate vectors for ... WebFFTW 2 had separate data types fftw_plan, fftwnd_plan, rfftw_plan, and rfftwnd_planfor complex and real one- and multi-dimensional transforms, and each type had its own ‘destroy’ function. In FFTW 3, all plans are of type fftw_planand all are destroyed by fftw_destroy_plan(plan). Where you formerly used fftw_create_planand fftw_oneto trt yemen https://bopittman.com
